2013-06-28block: add basic backup support to block driverDietmar Maurer1-0/+8
backup_start() creates a block job that copies a point-in-time snapshot of a block device to a target block device. We call backup_do_cow() for each write during backup. That function reads the original data from the block device before it gets overwritten. The data is then written to the target device. Currently backup cluster size is hardcoded to 65536 bytes. [I made a number of changes to Dietmar's original patch and folded them in to make code review easy. Here is the full list: * Drop BackupDumpFunc interface in favor of a target block device * Detect zero clusters with buffer_is_zero() and use bdrv_co_write_zeroes() * Use 0 delay instead of 1us, like other block jobs * Unify creation/start functions into backup_start() * Simplify cleanup, free bitmap in backup_run() instead of cb * function * Use HBitmap to avoid duplicating bitmap code * Use bdrv_getlength() instead of accessing ->total_sectors * directly * Delete the backup.h header file, it is no longer necessary * Move ./backup.c to block/backup.c * Remove #ifdefed out code * Coding style and whitespace cleanups * Use bdrv_add_before_write_notifier() instead of blockjob-specific hooks * Keep our own in-flight CowRequest list instead of using block.c tracked requests. This means a little code duplication but is much simpler than trying to share the tracked requests list and use the backup block size. * Add on_source_error and on_target_error error handling. * Use trace events instead of DPRINTF() -- stefanha] Signed-off-by: Dietmar Maurer <dietmar@proxmox.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2013-05-24coroutine: stop using AioContext in CoQueueStefan Hajnoczi1-1/+1
qemu_co_queue_next(&queue) arranges that the next queued coroutine is run at a later point in time. This deferred restart is useful because the caller may not want to transfer control yet. This behavior was implemented using QEMUBH in the past, which meant that CoQueue (and hence CoMutex and CoRwlock) had a dependency on the AioContext event loop. This hidden dependency causes trouble when we move to a world with multiple event loops - now qemu_co_queue_next() needs to know which event loop to schedule the QEMUBH in. After pondering how to stash AioContext I realized the best solution is to not use AioContext at all. This patch implements the deferred restart behavior purely in terms of coroutines and no longer uses QEMUBH. Here is how it works: Each Coroutine has a wakeup queue that starts out empty. When qemu_co_queue_next() is called, the next coroutine is added to our wakeup queue. The wakeup queue is processed when we yield or terminate. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2013-04-16use libusb for usb-hostGerd Hoffmann1-0/+4
Reimplement usb-host on top of libusb. Reasons to do this: (1) Largely rewritten from scratch, nice opportunity to kill historical cruft. (2) Offload usbfs handling to libusb. (3) Have a single portable code base instead of bsd + linux variants. (4) Bring usb-host support to any platform supported by libusbx. For now this goes side-by-side to the existing code. That is only to simplify regression testing though, at the end of the day I want remove the old code and support libusb exclusively. Merge early in 1.5 cycle, remove the old code after 1.5 release or something like this. Thanks to qdev the old and new code can coexist nicely on linux. Just use "-device usb-host-linux" to use the old linux driver instead of the libusb one (which takes over the "usb-host" name). The bsd driver isn't qdev'ified so it isn't that easy for bsd. I didn't bother making it runtime switchable, so you have to rebuild qemu with --disable-libusb to get back the old code. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2013-04-16hw/vmware_vga.c: various vmware vga fixes.Gerd Hoffmann1-0/+1
Hardcode depth to 32 bpp. It effectively was that way before because that is the default surface depth, this just makes it explicit in the code. Rename depth to new_depth to make it consistent with the new_width + new_height names. In theory we can make new_depth changeable (i.e. allow the guest to fill in -- say -- 16 there). In practice the guests don't try, the X-Server refuses to start if you ask it to use 16bpp depth (via DefaultDepth in the Screen section). Always return the correct rmask+gmask+bmask values for the given new_depth. Fix mode setting to also verify at new_depth to make sure we have a correct DisplaySurface, even if the current video mode happes to be 16bpp (set by vgabios via bochs vbe interface). While being at it switch over to use qemu_create_displaysurface_from, so the surface is backed by guest-visible video memory and we save a memcpy. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
